German construction firm小组已经透露，它首次使用3D打印来翻新现有建筑物。
In what PERI describes as a “world’s first,” its engineers are deploying aCOBOD3D printer to add an entirely new floor to a family home in the Bavarian town of Lindau. According to Dr. Fabian Meyer-Broetz, head of the firm’s construction 3D printing division, the project will see it break new ground, while exhibiting the technology’s potential for addressing applications other than erecting buildings from scratch.
“再次，我们将通过建筑3D打印技术进入新的领域，” Meyer-Broetz解释说。“从技术上讲，由于网站的斜率，打印机的设置尤其是一个新的挑战。Lindau的项目再次显示了这项新技术的灵活性和多功能性。”
PERI’s next-level renovation
由德国同胞建筑公司设计BODENSEE ARCHITEKTUR，Peri的房屋扩展正在与BALDAUF GEBÄUDEDRUCK, on the house of its owner André Baldauf. Already, the companies’ engineers have removed the building’s old roof and laid down a concrete ceiling, providing the basis for a new 3D printed floor.
一旦完成,扩展将测量约120square meters across and reach a height of 3.7 meters, but according to Baldauf, the project’s unique approach to construction could represent a breakthrough in itself. “The most important topics of our time are the careful use of our earth and the digitalization of all areas. The building industry has had few answers to these so far,” said Baldauf.
他补充说：“通过将高度二氧化碳结合的海王星草隔热，折叠的木制屋顶和3D打印的承载结构混合，我们能够以几乎二氧化碳的中性方式构造建筑物扩展。”“墙壁是计划并以3D印刷的，根据3D计划，木制的屋顶已绑起来，准备好组装。这就是我们今天的计划和建造方式。”
In practise, PERI is constructing its extension usingHeidelbergCement’s‘i.tech 3D’ material, which is custom-made for 3D printing, along with COBOD’sBOD2机器。据报道，在迄今为止的构建过程中，该系统已经显示出在现有结构中不均匀表面上打印的灵活性，从而有效证明了它不仅可以创建不仅仅是独立的建筑物。
释放BOD2
PERI’s Bavarian renovation project marks the latest in a string of collaborations with COBOD, a company in which it has been a shareholder since 2018. Over the last three years, the BOD2 has consistently proven itself to be a highly-adept house building tool, particularly given that it’s able to move into any position across three axes, without needing recalibration.
BOD2的打印速度为1 m/s，也是市场上最快的3D打印机之一，据报道它能够创建1 m雷电竞app下载2of double-skin wall every five minutes, while its safety certification allows engineers to complete manual tasks like pipework around it, expediting the house building process.
今年早些时候，Peri使用BOD2到3D打印完成了三层公寓楼in Wallenhausen, Germany, which is now expected to be rented out on the domestic market there. However, COBOD’s technology hasn’t been deployed exclusively by its part owner, rather it continues to be used extensively in construction projects around the globe.
U.S. non-profit人类栖息地is currently utilizing the BOD2 to3D print affordable housingof its own in Tempe, Arizona, which it intends to award to a family in need. Meanwhile, in a similarly charitable project in Malawi,14trees已经选择利用Corbod的技术来建造3D印刷学校，在向学生开放之前，在18个小时内这样做。
Beyond housing, the BOD2 has also found energy applications in the past, with COBOD,GE Renewable Energy和LafargeHolcimworking to3D print ‘record-tall’ turbine towerslast year. The project was set up to boost renewable energy production and lower its levelized cost, while exhibiting the BOD2’s capabilities, which LafargeHolcim has said “expand the realm of construction possibilities.”
Advances in 3D printed homes
Although COBOD has managed to establish itself as one of the leaders in the emerging construction 3D printing sector, it’s now beginning to face some stiff competition.ICONhas also become one of the industry’s early front runners, and it deployed its Vulcan 3D printing technology to build四间多层房屋in East Austin earlier this year.
Likewise,强大的建筑物has nowraised over $100 millionto fund the continued roll-out of its proprietary extrusion-based construction technology. In March 2021, the firm unveiled plans of its own to3D print a fifteen-strong neighborhoodCoachella Valley附近的房屋，其目的是在美国市场上列出59.5万美元至950,000美元。
On a more experimental level, firms likeWASPare also developing biomaterial-based construction approaches that could form the basis of a new eco-friendly house building model. The Italian 3D printer manufacturer finished building anorganic ‘TECLA’ housefrom clay in January, although it hasn’t yet been opened to members of the public.
